Although vastly different in size, NYC and San Francisco are the most closely related cities in the USA when it comes to urban density. It's not that much of a stretch to compare the two. A big difference is that in San Francisco it's very easy to wind up in a bad neighborhood. Some of the worst neighborhoods are right in the middle of the city. In New York, it's hard to wind up in a bad neighborhood, unless you live there. This is a return to NYC for me and it's interesting to see how much safer it is than it was even 10 years ago, when it was already much safer than the 1980s...
